Screw bottle capping machine’s structure

This automatic screw capping machine mainly consists of a conveyor belt, touch screen, side conveyor belt for bottle feeding, photoelectric detector, bottle fixing device, capping wheels, ordinary motor, stepping motor, handles, and so on. The equipment is adjustable according to the bottle’s height, mouth diameter, width(or diameter). Adjustable places include the conveyor belt width, side conveyor belt width, and height, the height of the capping device.

Details and functions of each part 

  • The touch screen: People are able to set the running speed of the conveyor belt and the time of capping on the touch screen.
  • Friction wheels: Rotate under the control of the motor, tightening bottles by the action of friction. The bottle moves forward on the conveyor belt. When the photoelectric eye detects a bottle, the equipment will fix the bottle, then four rotating wheels screw the cap driven by the ordinary motor. After capping, four friction wheels release the bottle cap.
  • Photoelectric eye: It can detect the bottle is going to the capping device.
  • Cap pressing device: Press the cap to prevent the bottle from slipping during the capping process. Since the cap has pressure on the bottle, it’s better to use relatively hard bottles.
  • The conveyor belt: Driven by a motor, the width of the conveyor belt can be adjusted according to the size of the bottle. Besides, it can be lengthened and widened if needed.
  • Bottle feeding conveyor belt: It can accurately send the bottle to tighten the cap. Two stepping motors control both sides of the conveyor belt. The operator can adjust the width of the side baffle to facilitate the clamping of the bottles. And the height of the bottle feeding conveyor belt can be adjusted. A handle can adjust the height of the side conveyor belt, which is convenient to fix the bottle and prevent the bottle from skewing during the capping process.

How the bottle cap tightening machine works?

Before entering the automatic capping machine, a cap falling machine usually is matched to put the cap on the bottle. When bottles go into the equipment, the conveyor belt transported the bottle to the side conveyor belt, which can clamp the bottle. Four wheels will screw the bottle cap tightly. After the capping of the bottle, these four wheels will release, and the final products move forward.

What fields are the screw capping machine used in?

The bottle cap tightening machine has a wide range of applicability in the industries of beverage, fruit juice, fruit tea, cough syrup, peanut butter, chocolate sauce, jam, chili sauce, sesame oil, skincare, alcohol, disinfectant, pesticide, detergent, liquid detergent, hand sanitizer, windshield washer fluid, etc.
